An alkene on vigorous oxidation with KMnO4 gives only acetic acid. The alkene is

A.CH3CH2CH = CH2

B.CH3CH = CHCH3✓ Correct

C.(CH3)2 C = CH2

D.CH3CH = CH2

Explanation

Since, the alkene on oxidation gives only acetic acid, therefore, the alkene must be symmetrical, containing two C-atoms on either side of the double bond i.e., 2- butene. 3 3 4 3 CH CH CHCH KMnO 2CH COOH ->
